bootnode -writeaddress is not working

[kinfkong]

When I run command:
/usr/local/bin/bootnode -genkey /tmp/tmp.txt -writeaddress
The -writeaddress is not working (no address output).
I view the code:
there is a return statement in the switch branch when -genkey is provided.
That is wrong.
See the following code line:

go-ethereum/cmd/bootnode/main.go

Line 72 in 6a33954
